Effect of slope on treetop detection using a LiDAR Canopy Height Model

ISPRS Journal of Photogrammetry and Remote Sensing, 2015
Canopy Height Models (CHMs) or normalized Digital Surface Models (nDSM) derived from LiDAR data have been applied to extract relevant forest inventory information. However, generating a CHM by height normalizing the raw LiDAR points is challenging if trees are located on complex terrain.

Assessing the Impacts of Various Factors on Treetop Detection Using LiDAR-Derived Canopy Height Models

IEEE Transactions on Geoscience and Remote Sensing, 2019
Canopy height models (CHMs) were utilized to detect treetops and estimate individual-tree parameters. The treetop detection based on CHMs was affected by surface topography and crown characteristics. However, their effects have not been well studied. Therefore, this paper aimed at assessing the impacts of aforementioned factors to facilitate treetop ...

Individual Tree-Crown Delineation and Treetop Detection in High-Spatial-Resolution Aerial Imagery

Photogrammetric Engineering and Remote Sensing, 2004
The cost of forest sampling can be reduced substantially by the ability to estimate forest and tree parameters directly from aerial photographs. However, in order to do so it is necessary to be able to accurately identify individual treetops and then to define the region in the vicinity of the treetop that encompasses the crown extent.
